-Disease causing microorganisms are known as pathogens and these pathogens are spreading disease directly among humans.

-Health risk associated with polluted water includes different diseases such as respiratory disease, cancer, diarrheal disease, neurological disorder and cardiovascular disease.

-Contaminated water has large negative effects in those women who are exposed to chemicals during pregnancy, it leads to the increased rate of low birth weight as a result fetal health is affected

Due to DO low in the water, the aquatic life will die.
The corpses are decomposed by the anaerobic bacteria, H2S and CH4 formed, the river will smelly

1. can disrupt ecosystem
eg: oxygen demand waste, inorganic waste
2. can cause health problem

# data[].attributes.body
- DO high then only can cause the aerobic

- organic waste get into the river, BOD increase, aerobic bacteria will use DO to dissolve organic waste

- if too many organic waste, DO <2mg/l, will cause the process from aerobic to anaerobic

- then when anaerobic, byproduct gas H2S and CH4 will be produce (BOD high while DO low)

- organic waste masuk, BOD increase, aerobic bacteria will use DO to dissolve organic waste

Inorganic pollutants like mercury, cadmium and Arsenic can enter into water source from various industries and from mining, ores. If these inorganic compounds present in water beyond normal limit, they cause serious health effects to consumers.

lead to poor water quality, while accidental oil spills and negligent industries emptying waste into water bodies are also key contributors.

Improperly discarded waste, such as fragments of plastic, rubber or other manmade materials, can find themselves into water sources and persist for a long time. Because they are too robust to dissolve in the water and too big to mix effectively with the molecules, they simply float on its surface and prevent oxygen and sunlight from penetrating below.

Fertiisers and pesticides applied to crops can seep into the ground and contaminate underwater rivers and waterbeds, thus compromising the quality of wells, boreholes and other places from which groundwater is extracted for human use.

When too much biodegradable material is added to water, the number of microorganisms increase and use up the available oxygen.

When oxygen levels in the water are depleted, relatively harmless aerobic microorganisms die and anaerobic microorganisms begin to thrive. Some anaerobic microorganisms are harmful to people, animals and the environment, as they produce harmful toxins such as ammonia and sulfides.
